State Machine Using Function Pointers

Code

#include <stdio.h>

void state_init()    { printf("Init"); }
void state_load()    { printf("Load"); }
void state_execute() { printf("Execute"); }
void state_exit()    { printf("Exit"); }

// Your logic here
void run_state_sequence(int start) {
    // Implement using function pointer array
    if(start==0){
        state_init();
        printf("\n");
        state_load();
        printf("\n");
        state_execute();
    }
    else if(start==1){
        state_load();
        printf("\n");
        state_execute();
        printf("\n");
        state_exit();
    }
    else if(start==2){
        state_execute();
        printf("\n");
        state_exit();
        printf("\n");
        state_init();
    }
    else{
        state_exit();
        printf("\n");
        state_init();
        printf("\n");
        state_load();
    }
}

int main() {
    int start;
    scanf("%d", &start);
    run_state_sequence(start);
    return 0;
}
